Specification of Letters Patent.

Patented Oct. 5 1915.

Application filed February 21, 1914. Serial No. 8:20,?512.

To all whom it may concern: I

Be it known that I, HARVEY C. Snnnnn, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Furniture Anchors, ofwhich the following isa specification.

My invention relates to furniture anchors and arms particularly toprovide a type of device that may be used in connection with schooldesks or similar furniture used in assembly halls in general, and alsoin connection with gymnasium appliances. It is frequently necessary i toremove this furniture for various purposes and this re.- moval hasalways been a source of a great amount of trouble. a

My invention aims to provide an attachment which may be permanentlyplaced in the floor, of the hall, being embedded therein in a mannerthat its upper surface will be flush with the surface of the floor. Anattaching structure of peculiar form is then caused to engage thefurniture and, by a slight rotation, this attaching structure so engagesthe member embedded in the floor in a manner to securely hold thefurniture in position; I also aim to provide a type of bolt for use inconnection with the member placed in the floor, which is such that thebolt itself may never pass entirely through the floor member. Further,this floor member and the attaching bolt are preferably so constructedthat the bolt is positively limited in its rotation, to lockitself inposition.

structure shown by me in the accompany ing sheet of drawings, in whichsimilar characters of reference designate corresponding parts, and inwhich:

Figure 1 is aview in perspective of a portion of a well known type ofschool desk shown held in position by the use of my invention, Fig. 2 isan enlarged side elevation of my furniture anchor showing a portion ofthe structure in section, Fig. 3 is a bottom View of the socket memberused by me, Fig. 4- is a section taken on line 44 of Fig. 2 and lookingin the direction of the arrows, Fig. 5 is a section taken on line 55 ofFig. 3, and Fig. 6 is a side elevation of the socket member used by me.

In illustrating my invention, I have any type of furniture Whereverconvenient.

In Figs. 2, 3, 5 and 6, I have shown a socket member which forms one ofthe essential features of my invention, this socket 7 member comprisinga body portion 5, being externally threaded as is shown at 6. EX-

tending centrally through this socket member is an elongated slot 7communicating at its lower end with a counterbored portion 8 ofsubstantially circular formation, although I have provided thiscounterbored portion with inwardly projecting shoulders 9, theseshoulders 9 having one side disposed substantially at right angles tothe long dimensionof the slot 7, as is shown at 10. Go-

operating with this socket member is a bolt 11 having a flattened anddrawn-out head, as shown at 13, this head being shaped somewhat similarto the slot 7 and being adapted to be inserted therethrough to rest inthe lower countersunk portion, as is more clearly shown in Fig. 2.Determinately spaced above the level of this head, I have provided twofins 14, these fins being set at such angle with respect to the head 13,that they will prevent passage of the entire bolt through the slottedportion, after the head 13 has been passed through this portion andgiven a slightturn to prevent its removal, it being understood that thehead 13 cooperates with the flat sides 10 of the inwardly projectingshoulders 9 tolimit the amount this bolt is turned. The upper end of thebolt is threaded as at 15, for the reception of a nut 16, which nut isadapted to hold a clamp 17 in firm engaging position with the furniture.This clamp 17 is provided with an overhanging tongue such as is shown at18 and also with a right angular upwardly extending arm 19 at its lowerend. This arm being of a width equal to the width of the bracket itself,Willprevent its easy rotation when the anchors are located in theircorrect position, it being understood that a number of these anchors areused for each piece of furniture.

' fins 1% engage the upper edge'of this slot,

socket member in position, the threads on the exterior of this socketmember serving as a means for retaining it in its position.

after its top is level With the top surface of the floor. 'The bolt 11is then dropped into position by permitting the head 13 to pass throughthe'slotted portion 7 and When the because of their peculiar angularposition, the bolt itself is given a bodily quarterly turn, which willbring the head 13 out of registration With the slot 7 and preventremoval of the bolt by an upward pull, be cause of the engagement ofthis head With the bottom Wall of the counterbored portion 8. Further,the shoulders 9 prevent an eX- cessive rotation of the bolt and thusinsure a correct pos1t1on.- The fins 14 not only serve the purpose oflndicatlng When'the bolt head has reached the countersunk portion 8, butalso prevent dropping of the bolt entirely through this socket member.After the bolt is in position, the bracket 17 is placed in'grippingengagement and the nut.

16 screwed home, thus firmly anchoring the furniture in position. e

What I claim, is 1. A furniture anchor comprising a socket member havingan elongated slot passing Qopies of this patent may be obtained for fivecents each, by addressing the Commissioner of Patents.

through its body, a bracket member adapted to engage the furniture, abolt and nut for engaging said bracket member and said socket member,said bolt being provided With ahead similar in shape to the slot in saidbody member said socket member being arranged to engage the head of thebolt When the bolt is given a partial turn and fins on said boltdisposed at such an angle with respect to its head to limit its throughsaid socket member.

2. Afurniture anchor comprising a socket member having an elongated slotpassing through its body, the bottom of said member, having asubstantially circular countersunk portion communicating with saidelongated slot, inwardly projecting shoulders in said countersunkportion, a boltand nut, a

passage.

flattened head on said bolt. adapted to fit b said, slot and engage theshoulders in said countersunk portion When the bolt is given a partialturn, fins on said bolt disposed at such an angle ith respect to its'headto limit its passage through the socket mem-. her, and a bracketmember for engaging the furniture and held on said bolt by saidnut.
